Three Golden Rules of Grammar

This is the gist of the mail I received from one of the e-groups I belong to. Those chaps are real brainy, I tell ya!

---

1. Remember to carefully avoid spilit infinitives.

2. Prepositions are something you should never end a sentence with.

3. Avoid, shun, and eschew all repetition, redudancy, and tautology.

And with reference to the second rule, there is one interesting quotation attributed to the Late British PM Winston Churchill - "This is the kind of nonsense up with which we should not put".

Sounds like a master grammarian, doesn't he?
